This study is a disease-based registry designed to follow patients with a DSM-IV-TR (Diagnostic and Statistic Manual of Mental Disorders, Text Revision) diagnosis of schizophrenia, schizoaffective disorder, or schizophreniform disorder treated in usual care settings for up to 5 years. The registry seeks to describe the course of disease in schizophrenia, including cognitive function and negative symptoms, its treatment, and its burden of disease for participants, caregivers, clinicians, and society as a whole.
